Portefeuille intelligent

Ines SARRAY & Rahma DAIKHI

The user take his intelligent wallet like he's used to. When he opens the wallet, the embedded light sensor will detect this action and send a notification event to the attached GPS Module.

The GPS module will get the user location coordinates, then, using Google Maps, it will convert this coordinates into an address.

These addresses are then stored into a file for further processing.

• 1 x Light Sensor | reseller link | 507010 | technical document
• 1 x GPS sensor | reseller link | Ev. Kit PA6B | technical document
• Raspberry Pi | reseller link | Rev. B | technical document
• 1 x ADC microchip | reseller link | MPC3202 | technical document

• The system (wallet) components are connected via UPnP
• When the Light Sensor detects a positive illumination change (lights), it sends an event to GPS Module
• The GPS Module will send a read data request to the GPS chip (connected via usb-to-serial port)
• Once the coordinates answer is received, it is parsed into longitude and latitude values
• The GPS Modules sends these values to Google Maps, using Geocoder API, to do reverse decoding and get back the address
• The address is stored for further usage (monitoring, spending pattern etc)

1. Sensors Module container: with Light sensor and GPS
2. Location Module container: connects to Google Maps to get location address, stores data and defines spending patterns

1. Monitoring user location
2. Strong information about user spending pattern
3. Improve user money management
4. Can be coupled with other services via UPnP

The LightSensor uses Raspberry.IO.Net Library to communicate with LightSensor module through Analog-to-Digital Converter (MCP3202) via Raspberry SPI/GPIO ports

Sensor light Beans and source code

GPS Module uses serial communication with GPS sensor to get coordinates, than uses Google Maps API to get actual location from coordinates

GPS Beans and source code

• Configure Raspberry Pi IP address
• Install mono framework
• Install GPIO SPI Driver (for communication with mpc3202 adc)
• Install WComp Linux container
• Copy WComp beans dll (LightSensorBean.dll, GPSBean.dll) under WComp container beans folder

We communicated with Reims using www.adhoccollaboration.com platform,

We've sent him specifications and trials results, the proposed prototype was satisfying, but missing some functionalities (like having a proper encloser for the light sensor inside the wallet)

Currently the Wallet uses only Light sensor to detect when it's opened and GPS to get user's location

• We could add a sensor to count the money contained in the wallet

• Hold an account of the credit available in the wallet
• Define user spending pattern
• Change data storage from files to database

• Notify the user when he's running low on credit
• Notify the user when his spending pattern changes
• Notify the user if his wallet is stolen or lost

• Show spending pattern as a graph
• Show cash crediting and cash spending on a map
